Warts are common skin growth that many people encounter at some point in their lives. Warts might not be dangerous, but they can be annoying, embarrassing, and sometimes painful. You may have a wart on your finger, foot, or even near your eye. While often harmless, they can be unsightly, uncomfortable, and sometimes persistent.  Understanding what causes warts, how you can get them removed safely, and whether warts are contagious or not, can empower you to take effective action.

Let’s break down everything you need to know about this common skin issue in a clear and easy-to-understand way.

What is a Wart?

A wart is a small skin growth caused by the human papillomavirus (HPV). The virus enters the skin through a tiny cut or scratch, leading to extra skin cell growth. This creates the raised bump called a wart.

These growths can appear anywhere on the body, including the scalp, nose, near eye, and even eyelid. Warts are contagious and can spread through direct contact or shared surfaces.

Some people refer to warts as verrucae. So, if you hear the term “wart and verruca”, it’s often describing the same thing, just in different locations.

What Causes Warts?

The main reason for warts is HPV infection. There are more than 100 strains of HPV, and different types cause different kinds of warts. You might get the virus by:

  • Touching a wart on someone else
  • Walking barefoot in public showers or pools
  • Sharing personal items like razors or towels
  • Scratching or picking at an existing wart and spreading it to another part of your body

Factors that increase the risk of wart infection include:

  • Direct contact with a wart or surfaces touched by someone with a wart.
  • Lowered immune system, making it harder to fight the virus.
  • Damaged skin, such as cuts or abrasions, provides an entry point for the virus.

Yes, warts are contagious, but they don’t spread like common cold or influenza. It usually involves broken skin and direct contact for transmission.

Types of Warts and How to Identify Them

Not all warts look the same. Here’s how to identify a wart based on their sites and behavior:

TYPE OF WARTAPPEARANCECOMMON  SITESNOTES
1.Common WartsRough, raised bumps, often with black dotsHands, fingers, knees, elbows, or any parts of the bodyUsually asymptomatic
2.Plantar WartsHard, grainy growthsSoles of the feet or between the toes May hurt while walking Should be differentiated from callus 
3.Flat Warts or plane wartSmall, smooth, skin colored, flat-topped lesionsFace, dorsum of the handUsually affects children 
4. Filiform WartsLong, thin, thread-like projectionsFace, around the eyes and mouthGrow quickly Should be differentiated from skin tags
5. Periungual WartsRough, irregular growthsAround fingernails and toenailsCan cause pain and nail damage
6. Genital wartsGrayish small papules or pediculated grayish cauliflower mass (condyloma acuminatum) Vulva, vagina, Cervix in female Glans and penis shaft in male Transmitted through sexual contact

Sexual partners of genital warts patients should be examined and followed for 2 years.

Complications:
Condyloma acuminatum of the cervix could be huge and obstruct normal delivery, leading to cesarean section. 

Genital warts of the cervix could lead to intraepithelial neoplasm, which is a premalignant condition. 


Warts, especially genital warts, should be evaluated by a dermatologist as soon as possible to mitigate their growth and get the proper wart treatment.

Are Warts Dangerous?

Most warts are harmless, but they can cause:

  • Discomfort or pain (especially plantar wart or periungual warts)
  • Aesthetic embarrassment (especially eye, hand, or genital warts)
  • Spread to other parts of the body or other people

Wart Treatment Options

There are various methods for wart treatment, ranging from home remedies to professional treatments:

Home Treatments (used under the supervision of a Dermatologist)

  • Salicylic Acid Products: Available as wart cream, wart lotion, wart solution, wart pads, or wart patches. These products work by peeling away the infected skin. 
  • Cryotherapy Kits: Freeze the wart, causing it to fall off over time.

Wart and Skin Tag Removal: Common areas of confusion, what’s the difference?

Warts and skin tags are both skin bumps, but they’re not the same. 

Skin tags are soft, harmless skin flaps and are not contagious, nor are they caused by a virus. They are benign overgrowths of skin. They’re more common in people with diabetes, obesity, or hormonal changes.

Treatment OptionUsed for WartsUsed for Skin Tags
CryotherapyYes Sometimes used for small skin tags
Surgical ExcisionNoYes, it offers quick removal
Chemical cauteryYes Not typically used for skin tags
Laser RemovalYes, especially for stubborn or facial wartsYes – effective for hard-to-reach skin tags

Prevention: How to Stop Warts from Coming Back

Preventing warts starts with simple habits:

  • Wear sandals in public showers or gyms
  • Don’t touch or pick at warts
  • Keep cuts and scrapes clean and covered
  • Don’t share towels, razors, or nail tools with anyone
  • Consider the HPV vaccine, which protects against the types of HPV that cause genital warts
